RE: A-7 Corsair Upgrade
3-4 lbs. should be very do-able with film covering and attention to the amount of glue used. I'm also not convinced flaps on a model of this size are needed nor offer much benefit. Eliminating those will save an ounce or so. Do that a few times and the weight will be reasonable for the Toki.
BTW, I also have a DJ-1 sitting here ready to fly. It's been in that state for over a year [sm=eek.gif]. I just haven't had time to run in the engine and take it out to the field.
I remember hearing some time back that Toki was supposed to release a slightly larger engine than the current .18. Did anything ever come of that?
